Following growing interest in the use of ammonia as a fuel in solid oxide fuel cells (SOFCs), we have investigated the possible reaction between the apatite silicate/germanate electrolytes, La8+xSr2−x(Si/Ge)6O26+x/2, and NH3 gas. We examine how the c... Read More about Formation of apatite oxynitrides by the reaction between apatite-type oxide ion conductors, La8+xSr2-x(Si/Ge)6O26+x/2, and ammonia.

Synthesis and characterisation of the quaternary nitride-fluoride Ce2MnN3F2-δ (2009)
Journal Article

Ce 2 MnN 3 F 2-δ has been synthesised via low-temperature fluorination of the ternary nitride Ce 2 MnN 3 . To the best of our knowledge, Ce 2 MnN 3 F 2-δ is the first quaternary nitride-fluoride to be reported. The reaction of Ce 2 MnN 3 with 10% F 2...

Transition metal pnictide-halides: A class of under-explored compounds (2009)
Journal Article

In terms of application, mixed anion compounds have attracted far less attention than mixed cation systems. Interest in the catalytic properties of nitrides has been driven, in part, by their accessibility through new, improved synthesis routes. Alth...

Increase in magnetoresistivity in Ba2CoS3 via Zn2+/Co2+substitution (2009)
Journal Article
Harrison, M. R., Hardy, V., Maignan, A., & Francesconi, M. G. (2009). Increase in magnetoresistivity in Ba2CoS3 via Zn2+/Co2+substitution. Chemical communications : Chem comm / the Royal Society of Chemistry, 2214-2216. https://doi.org/10.1039/b817363j

We report an increase of negative magnetoresistivity from 1.7% to 9% in the Ba2Co0.5Zn0.5S3 series (0 <= x <= 0.5), derived from Zn2+/Co2+ substitution in Ba2CoS3; Zn2+ substitution destroys the one-dimensional antiferromagnetic ordering typical of B...

An investigation of the high temperature reaction between the apatite oxide ion conductor La9.33Si6O26 and NH3 (2009)
Journal Article
Kendrick, E., Headspith, D., Orera, A., Apperley, D. C., Smith, R. I., Francesconi, M. G., & Slater, P. R. (2009). An investigation of the high temperature reaction between the apatite oxide ion conductor La9.33Si6O26 and NH3. Journal of Materials Chemistry, 19(6), 749-754. https://doi.org/10.1039/b808215d

There is growing interest in the use of ammonia as a fuel in Solid Oxide Fuel Cells (SOFCs). However, the possible reaction between the electrolyte and ammonia, and its potential effect on performance, has received little attention. In this paper, we...
